Abstract

In this research, we studied the cleanliness of a developed aqueous stripper with optimized mixing ratio of the water and solute components. The stripping properties of an organic stripper were compared with those of the aqueous stripper, and the electrical and optical properties of the stripped specimen with a coated ITO film layer on glass were evaluated. From the result of the PR stripping process of the aqueous stripper with optimized water content and organic stripper, the aqueous stripper showed equal or better stripping capability than the organic stripper. In the case of the aqueous stripper, PR was floating in the stripper liquid through swelling and tearing, whereas the organic stripper showed dissolution of PR into the stripper liquid. Based on the difference in stripping mechanism between the organic and aqueous strippers, we estimated greenhouse gas (GHG) emissions and the amount of wastes in each stripper.
